NACE MR0175, inozivikanwawo se "Standard Material Requirements for Resistance to Sulfide Stress Cracking in Corrosive Petroleum Refining Environments," chiyero chakagadziridzwa neNational Association of Corrosion Engineers (NACE) kugadzirisa nyaya ye sulfide stress kupaza mumafuta uye. indasitiri yegasi. Iyi chiyero inopa nhungamiro yekusarudzwa uye kukodzera kwezvinhu zvinoshandiswa mumidziyo uye zvikamu izvo zvinozoratidzwa munzvimbo dzinoparadza mumabasa ekunatsa peturu.
Sulfide stress cracking (SSC) imhando yehydrogen-induced cracking inoitika musimbi nemamwe maalloys kana yaiswa hydrogen sulfide (H2S) uye stress. Rudzi urwu rwekupaza runogona kukonzeresa kutadza kwakaipisisa kwemidziyo uye kuunza kuchengetedzwa kwakakomba uye njodzi dzezvakatipoteredza mumabasa ekunatsa petroleum. NACE MR0175 yakagadziridzwa kuderedza njodzi yeSSC nekupa zvinodiwa pakusarudzwa uye kukodzera kwezvinhu zvinopokana ne sulfide stress kupaza.
Iyo chiyero inovhara zvakasiyana-siyana zvezvinhu, zvinosanganisira kabhoni uye yakaderera-alloy simbi, Stainless simbi, nickel alloys, uye mamwe alloys asingadzivirirwe. Inopa nhungamiro yekusarudzwa kwezvinhu, kurapwa kwekupisa, kuomarara miganhu, uye kuyedza zvinodiwa kuti ive nechokwadi chekuti zvinhu zvinoshandiswa mupetroleum yekunatsa mashandiro zvinopokana ne sulfide kusagadzikana kupaza.
Chimwe chezvinhu zvakakosha zveNACE MR0175 ndiko kukodzera kwezvinhu kuburikidza nekuyedza uye zvinyorwa. Iyo chiyero inodonongodza zvinodiwa zvekuyedzwa, senge kuomarara kuyedzwa, kuyedza kusimba, uye sulfide kusagadzikana kuputsa bvunzo, kuratidza kupokana kwezvinhu kune sulfide kusagadzikana kupaza. Uye zvakare, chiyero chinoda kuti vagadziri vape zvinyorwa, senge zvinhu bvunzo mishumo uye zvitupa zvekuteerera, kuratidza kuti zvinhu zvacho zvinosangana nezvinodiwa zveNACE MR0175.
NACE MR0175 inopawo nhungamiro yekugadzira uye kugadzirwa kwemidziyo uye zvikamu zvekudzikisa njodzi yekupwanya sulfide kusagadzikana. Izvi zvinosanganisira kurudziro yewelding maitiro, kurapwa kwepamusoro, uye mamwe matanho ekudzivirira hydrogen-induced kupaza mumunda.
Kutevedzera NACE MR0175 kwakakosha pakuona kuvimbika uye kuvimbika kwemidziyo uye zvikamu mumabasa ekunatsa petroleum. Nekusarudza uye zvinokodzera zvinhu zvinoenderana neyakajairwa, vashandisi vanogona kudzikisa njodzi yekupwanya sulfide kusagadzikana uye kuve nechokwadi chekuchengetedza uye kugona kwezvivakwa zvavo.
Mukupedzisa, NACE MR0175 chiyero chakakosha cheindasitiri yemafuta negasi, ichipa nhungamiro yekusarudzwa uye kukodzera kwezvinhu zvinopikisa sulfide kusagadzikana kupaza munzvimbo dzinoparadza petroleum yekunatsa. Nekutevera zvinodikanwa zveiyi chiyero, vashandisi vanogona kudzikisira njodzi yekupwanya sulfide kusagadzikana uye kuve nechokwadi chekuvimbika uye kuvimbika kwemidziyo yavo uye zvikamu. Kutevedzera NACE MR0175 kwakakosha pakuchengetedza kuchengetedzwa uye kugona kwepetroleum refine operations.
